SNOW-PLOW.

SPECIFICATION forming part of Letters Patent No.392,850, dated November 13, 1888.

(No model.)

To aZZ whom it may concern.-

Be it known that we, RICHARD W. CAMPBELL and JOHN E. WARD, both residents of Huron,in the county of Beadle and Territory of Dakota, have invented certain new and useful Improvements in Snow-Plows; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyingdrawings, which forma part of this specification, and in which- Figure l is a side View of our improved snowplow. Fig. 2 is atop plan view of the same. Fig. 3 is an end view, and Fig. i is a top plan View showing the attachments employed when the plow is used in towns and cities.

Similar letters of reference denote corresponding parts in the several figures.

Our invention has relation to that class of devices known as snow-plows, which are adapted to be attached the front of a locomotive; and it consists in the construction of such a device that will effectively clean from the track snow just fallen or snow after the top has become crusted from rain or thaw; and it further consists in the arrangement of removable parts whereby the snow, after having traveled up theinclincd top of the plow, is deposited into cribs removablysecured to the sides thereof,(when the plow is used in a city,) which can. be emptied of their contents at any suitable point along the track when they become filled with snow,

To this end our invention consists in the improved construction and combination of parts of such a device, as will be hereinafter more fully set forth.

In the accompanying drawings, the letter A denotes the body of the plow,suitably mounted upon wheels B, and provided with a compartment,O, for'the workmen, who enter through a door, D, in the rear body portion of the plow. This body is provided with the inclined top E, formed of two parts, the rear part of which is hinged to the rear edge of the front or station ary part in any ordinary manner, and is provided with an elongated aperture, F, the object of which will be presently described. The body is further provided along its inclined edge with side pieces, G, formed with opposite openings, H, the lower edges of which are provided with wearing -strips I. The forward edge of the stationary inclined top piece is .provided with a serrated or saw-edge cuttingstrip, J,whieh is secured thereto and is braced by the metallic sheet J, and the forward inclined edges are provided with similar cuttingstrips, K, which overlap two curved wings or shields,K,the object of each being to force the snow to one side, so as to allow the plow to pass through a snow-drift with the least pos sible friction and to prevent the snow from clogging against the sides of the plow.

K denotes the cutter-strips secured to the forward upper inclined edges of the inclined side pieces, the construction of which is substantially the same as the cutter-strips hereinbefore described.

L indicates the vertical cutters, which, after thesnow has been moved aslight distance upon the inclined top piece through the forwardmovement of the plow, will cut the mass ofsnow into strips which are not so liable to clog the way. Secured to this stationary inclined top piece at a distance to the rear of the vertical cutters is a standard, M, formed with a longitudinal. slot, N, in which removably secured fit the curved deflectors N, which extend with their rear ends through the rear of the opposite openings hereinbefore mentioned. This style of deflectors is employed when the plow is used in rural districts, the deflectors throwing the snow oif the track to the sides thereof, while the serrated cutter-strips easily saw through the crusted snow or ice, as will be readily understood without requiring an extended explanation. Now, when the plow is used in towns and cities, these curved deflect ors are removed, and the curved deflector O employed. This deflector is provided on its rear face with. strengthening-pieces P near the upper and lower edges, and through which pieces project a pivot-rod, p, which extends from the floor of the compartment and passes through the elongated aperture in the hinged top piece, this aperture permitting of the said hinged top piece being raised. for ventilation or for sliding the snow off of it which has accidentally fallen over the top edge of the deflectors. It will now be seen that when the plow is equipped with the pivoted or swinging deflector, as shown in Fig. 4 of the drawings,the sides of the plow beneath the lower edges of the opposite openings being provided with cribs Q, having outwardly-opening doors in its bottom, this deflector may be swung to one side or to the other, so as to guide the snow into each crib. This construction of snow-plow obviates the great drawback heretofore experienced with the plows now in use, which throw the snow in a continuous bank or ledge,which greatly interferes with the travel of persons and teams across the tracks, while with our device, constructed as shown in Fig. 4, and which, as hereinbefore stated, is adapted to be used in cities and towns, the snow is guided into each crib, which, after becoming filled, may be emptied at any desired point along the track, thus not interfering with travel in the streets.

Having thus described our invention, we claim and desire to secure by Letters Patent of the United States- 1. The, combination, with the body of the plow having an inclined top and side pieces formed with opposite openings, of a cuttingstrip secured to the lower front edge of the stationary inclined top piece, cutting'strips secured to the front inclined edges and to the upper inclined edges of the side pieces of the said plow-body, and removably-secured curved deflectors, the rear ends of which project through the openingsin the said side pieces, substantially as set forth.

2. The combination, with the body of the plow having an inclined top and side pieces,

the latter of which are formed with opposite openings, of a serrated cutting-strip secured to the lower front edge of the said inclined top piece,similar cutting-stripssecured to the front 0 inclined edges and to the upper inclined edges of the side pieces, vertical cutters secured to the inclined top at the forward portion thereof, a slotted standard, curved deflectors removably secured with their forward ends in 5 the said slotted standard and projecting with their rear ends through the opposite openings of the side pieces, and curved wings or shields secured to the forward outer inclined edges of the side pieces, substantially as set forth.

3. In a snow-plow, the combination of the inclined top piece formed of two parts,the rear one of which is hinged to the rear edge of the front part, and the sides formed with opposite openings, with the curved deflectors removably 5 5 secured to the said top piece.

4. In a snow-plow, the combination, with the inclined top piece and the side pieces formed with opposite openings, of the curved deflectors removably secured to the said top 60 piece, and cribs removably secured to the sides of the body of the plow beneath the 0pposite openings.

In testimony that we claim the foregoing as our own we have hereunto affixed our signa- 65 tures in presence of two witnesses.
